Abstract: Investigations are performed, how much primary coolant gas is released when liner leaks occur. In simplified models for calculations a cleft between liner and concretewith an uniform width h in the (im-range is assumed. Leaking gas flows along the cleft and percolates into the concrete. The flow rates depend very strongly on h. In connection with a venting channel system lying nearby the liner it is demonstrated, that for clefts in the range 5 $\mu$m gas percolates quickly into the concrete. For separations of 50 $\mu$m a large expansion in the concrete-liner interface is to expect, supposed the concrete is not cracked. Experimental results are discussed. Simple estimations show that the gas flow rates of liner leaks suggest clefts between liner and concrete in the range 5 - 5 0 $\mu$m.
